This invention relates 'to lubricating devices, and .niore particularly to lubricating devices -ior iocoinotive wheels. v

in a prior batent No. 1,241,343, granted September 25, 19.17, ll have described and claimed a hub platefior locomotive wheels, which is rovided withrecesses for thereception oi) lubricant andin which `the'lubiicant is delivered thereto vthrough a passage lo from the outside oi the wheel. 'y

in 'more recent .locomotive construction, the bearing boxes are placed on the outside of the wheels and Vthe engine frame is arranged on the'outside of the wheel with the driving gears arranged on the inside. The construction shown in nay prior patent is not particularly adapted for use inthe lubrie cation of locomotive wheels oi this character.

In the present invention, I provide 4a lubrieating device which may be employed either onthe outside or the inside of a locomotive wheel, depending upon the 'position oi the bearing box. ln this inventiongti provide a hub liner arranged between the hub oi the wheel and the bearing box and provided with recesses for the reception of lubricant. rlhe hub of the wheel may be providedwith si'rnilar recesses and suitable passages are arranged in the bearing boxthrough which the lubricant is delivered. y

ln the accompanying drawings,fgI have shown one embodiment ofthe invention. in this showing:

lligure` l is a'vertical sectional view oi a f locomotive axle and wheel showing the invention applied, ;f Figure 2 is a vertical. sectional view on line 2--2 of Figure 1w. Figure 3 is a horizontal sectional view on 4a lineS-B oligure 1, f

' .Figure l is'anelevation oi the hub of a locomotive wheel showingrecesses formed in the facaand,

Figure 5 is a front elevationoi the bearing box and hub liner removed/ Referring to the drawings, the reference numeral 1 desi natos an axle of ordinary construction, a apted to receive a locomotive wheel 2. The wheel is provided with a 5'@ hub 3 having an opening for the receptionoi the axle and the tace of the wheel adjacent the bearing box may be provided with spaced concentric recesses 4f". A bearing boxe@4 is arranged on eitheniside oi the wheel" and adapted to receive a portion oi the axle. The bearing box is provided with the usual ythrough the hub liner.

lubricant cellar 6, in which packing may be 'arranged and this llubricant cellar is retained in position by means of bolts 7. The bearing box may -be further provided with o0 the usual bearing box brass- 8, contacting with the upper halt of thev axle. A hub `liner 9 is arranged between the hub of the wheel and the bearing box and this hub liner is secured to the bearing box in any suitable t5 manner, as by means oi bolts 10 passing through ears 10 'formed on the liner and bearing box outwardly of the hub oi the wheel;` The shape and size of the hub liner may, of course, be varied according tothe 7@ design of the bearing box; The hub liner is provided with circularly arranged `recesses 11 arranged the same distance from the center oi the axle as the recesses 4 in the hub and adapted to .coincide therewith as the wheel revolves. The liner is shaped as shown in Figure 5, being provided in one side with a lateral opening 11" through which the axlemay pass when the liner is placed in position. The bearing box is provided with a lpair of longitudinal passages 12, which may be connected by a transverse passage 13. Grease cups la are arranged at the outerv v end of these passages and these cups are 85 provided with illing plugs 15. A similar grease cup 16 may be arranged on top of the bearingbox at the upper end of a vertical passage 17, communicating with the transvverse passage 18. As shown, the inner ends of the passages 12 communicate with a pair of the recesses 11,k which extend entirely rlFhe operation of the device will be apparent from the foregoing description. Locomotive wheels are lubricated with a relatively heavy non-iiowing grease generally known as driving box grease or pin grease.` This lubricant is heavy and will not iiow. By filling the cups 14 and 16, "and lthen screwin do theplugs` inwardly, the lubricantis torce through vthe passages 12 and the upper re- Jcesses 11, whence it is taken up by the recesses 4 in'the hub to lubricate .the hub of the wheel as the locomotive wheel revolves. When a bearing box is arranged on the outside oithe wheel, the wheel may be lubricated without getting under the locomotive. Pan ticular attention is invited to the fact that the liner 10 may be replaced when desired no or necessary without dropping the wheel of thejiocomotive. The fastening means for the nell liner are arran ed outwardl of the hub of the wheel 4to permit them .te he inserted and: 'removed withoutv disturbine'l thawheel and improvement over similar devices which cant passageway therein and previously have beenused, such devices being oi;E such character as to require that a locomotive be lashed up andthe wheels' dropped when it becomes necessary :to ire-- place a hner.

lt is to be understood that the form of invention herewith shown and described is to be taken as a .preferred example oi the saludandthat various changes in the shape, size, and arrangementv of parts ma be resorted to without departing from t e spirit of the invention or the scope of the subjoined claims. V

I claim:

v 1. The combination of a wheel includin ahub having a flat bearing face provided with lubricant receiving recesses, an axle for the hub,a bearing box having a lubriroyided 'with a wholly dat face adjacent t e hub ofthe wheel, and a hub liner carried by `said bearing box against the flat face thereof and fitted against the bearing face of said hub, said liner havin a plurality of recesses in the face thereo adjacent the hub of the wheel and being provided with an opening communicating between one of said last named recesses and the lubricant passage- Way ofsaid bearing box, the recesses of said liner being4 adapted to successively register and communicate with the recesses of said hub as the wheel rotates.

, means for forcing lubricant under pressure recesses, an axle vfor the hub, a bearing box for the axle provided with a pair of bricant passage-ways f extending therethrough,

through said passagoways, the face of said bearing box adjacent the hub ofthe wheel being dat throughout its area, and a hubliner corresponding in sha e to and arranged agaim the flat face of sald bearing box and secured to said box outwardly of said hub,

llidddgidtl said liner being provided inone face with plurality of lubricant recesses corresponding in arrangement to the recess'esm said hub and adapted to successively register therewith as ythe wheel rotates, a pair of said 'last named recesses communicating with said lubricant passage-ways to receive ,lubricant therefrom.

'Ehe4 combination of a lwheel including a-hub hayin'gia ilat bearingface, an axle for the' hub, a Vbearing'box' having a lubricant passageway therein 4 and provided with a wholly flat face'arranged adjacent and parallel to the bearing face ofthehub, and a* flat hub liner arranged between thehub of the wheel and said bearing box and secured against the at face thereof, said liner being provided in one edge thereof with a lateral opening through which the axle is adapted to move whereby said liner is adapted to v be inserted in position laterally with respect to said axle, said liner being providedrwith a plurality of recesses in the face thereof adjacent' the bearing face of the 'hub and being provided with an opening communi eating between one kof said recesses and the lubrlcant passage-way of said bearing box.

4. The combination of alwheel including a hub having a flat bearing face provided j with lubricant receiving recesses, an axle for the hub, a bearing box having a lubricant passage-way therem andprovided with a wholly fiat face arranged adjacent and par `allel to the bearing'face of the hub, and a fiat hub liner arranged between the hub of the wheel and said bearing box andsecured `against the flat face thereof, said liner being provided in one edge thereoflwith a lateral -opening throul h which the axle is adapted to move where y said liner is adaptedto be inserted in position laterally with respect to said axle, said liner being provided with a plurality of recesses' in the face thereof ad]acentl the bearing face of the hub and being provided with an opening communi eating between one of said last named recesses andthe lubricant passageway of said bearing box, the recesses of said. liner being adapted to successively register and communicate with the recesses of said hub as the wheel rotates.
